The requested lookup key was not found in any active activation context.

Normally I’m an up-to-date kinda guy so on my Windows XP install (through VMWare Fusion), I have the latest beta IE 8 running. Then I do my IE 6 testing through IE Tester. This normally works fine until recently I had a problem with Wufoo forms. Any page with a Wufoo form on it wouldn’t load in IE 6. I contacted them and they said they’ve seen the same thing, but only through “virtualized” renderings of IE 6, not through “real” installations. So I decided I was gonna uninstall my way back down to IE 6 and see if that would work. First you uninstall IE 8, restart, which brings you to IE 7. Then you uninstall IE 7, restart, which brings you to IE 6 (friggin seriously).

Fortunately, this worked, and it wasn’t Wufoo at all, those pages were running fine in a “real” instance of IE 6. But now I have a problem with a site in IE 7. IE Tester can’t test IE 7 unless you actually have it installed, so I needed to go back to Microsoft.com and install IE 7. And…

WTF. Great time for a nasty weird error with no solution in sight. I hate Windows. This is what happens when you click to download IE 7. You can close it, but then no download starts.

  1. I haven’t had this problem… but google-ing for an answer I came across this article:

    It talks about a second way to “manually” uninstall IE7:

    Sounds like this problem can be caused when you have part of the IE7 installation still hanging around.

    Hope this helps.

    Thank Jeremy! I think that’s exactly what the problem was. A little clean up and another restart and I had IE 7 back going again.
